Doug,While the module may be past its workmanship warranty period, if the defect affects the module's power output.... then i would argue that the power output warranty should cover it.  That warranty should be good for 25yrs.Anyone care to comment on that reasoning?

I think that one module with this issue along the frame will eventually fail.  But we are past the 2 year warranty of defects at this point.
